Kyohei Tachibana is a student at a culinary arts school with dreams of someday becoming a patissier (pastry chef). The next step in achieving this goal is to travel to France for some further studying, but there's just one problem: He can't afford it. Instead of giving up on his goal, he gets a part-time job as a cook for a group of four girls; Meg, Jo, Amy, and Sei.
The girls, ranging in ages of eleven to nineteen, turn out to be mercenaries. Despite the fact they're usually being shot at, they all happen to wear the scantiest and tightest choice of clothing possible, which seemingly increases their mobility during combat. Meg is a mechanic and damsel in distress, Jo is a psychotic sharp-shooting prodigy (as well as the pilot for their mecha, Jango), Amy is a computer whiz, and Sei is their boss, who in turn, works for Bai Lan

She has superhuman abilities from her artificial creation, usually followed by the appearance of a glowing tattoo on her left arm and shoulder blade. They resemble wings and are often called "The Wings of the Devil" and will glow when Jo is put under a lot of stress when fighting. Jo also puts Meg over anything else, which she stated when telling Meg that she fights for her only. When she is not fighting, she enjoys watching horror or gore related movies. Jo would eventually rediscover her past as a genetically engineered war machine in human form. After being forced to surrender with Meg and others held hostage, Jo returns to the secret labs for reprogramming and conditioning at RAPT R&D. Jo's counterpart, Maria, freed her to only prove who was the strongest; Jo managed to remove her will to defeat her and restores her true humanity. Jo realized that she has to destroy RAPT at the source all for all that has happened as well as help Sei. Meg was highly opposed to the idea after seeing her go through a lifetime of combat and feels it's not their problem.
